W. F. Yahya, Doaa ; Kolařík, Vladimír (referee) ; Štencl,, Jiří (referee) ; Šandera, Josef (advisor)
Thin layers are widely used in many fields of technology and today we can say that they are found in all modern technologies. Thin layers can be created in two ways, namely by chemical or physical means. This work focuses on the latter method, more particularly a technology of thermal evaporation of thin layers in a vacuum. The work focuses on the process principles during and after the evaporation. Much of the work focuses on the development and design of experiments. These experiments illustrate some of the phenomena that take place on thin films produced by the aforementioned technology. Work helps to better understand processes during formation of thin layers and properties that influence the quality and stability of thin films. In conclusion we describe results of experiments and new developments in the field of thin films deposition using evaporation under vakuum are summarized.

Junková, Anna ; Chejnová, Pavla (advisor) ; Janovec, Ladislav (referee)
Taboo and noa in communication. Realization of linguistic taboos in the print media. This thesis deals with issues of the taboo and noa in language and communication. The core of this thesis is to identify the essential tabooed themes in contemporary society and ways of their linguistic realization in the print media. In the theoretical part of this thesis is the first explained substance of the terms such as taboo, noa, communication and linguistic taboos with regard to the interrelations between these terms. In the empirical part are then defined tabooed themes occurring in the concrete texts of the diary Mladá fronta DNES and Blesk and of the periodical Rytmus života and ways of their linguistic grasping. The thesis focuses above all on the manifestations of speech restrictions in the lexical plan of the language.

The impact assessment of water treatment plants on water quality in the recipient
Kunert, Michal ; Benešová, Libuše (advisor) ; Šťastná, Gabriela (referee)
Watercourses influenced by anthropogenic activity increases in recent years and streams lose their natural character. This situation is critical particularly in small streams with minimal flow rates. The present work deals with the assessment of streams affected by discharges of treated wastewater from small waste water treatment plants. The results showed that in case of average flow in the recipient none of the monitored waste water treatment plants do not negatively affect the stream. Problems can occur when snow melts, when the lower temperature of the flowing water in the wastewater treatment plants negatively affect biological cleaning processes.

Vliv srážkových vod na provozování kanalizační soustavy a čistírny odpadních vod
Lysák, Martin
This thesis deals with current issues in the discharge of waste water from the urbanized area. The main aim is to evaluate the impact of rainwater on the existing unified sewerage system and the wastewater treatment plant in Brno. The theoretical part includes a brief assessment of the current state of the sewerage system of the city of Brno and the basic concepts as well as their use in everyday practice. The practical part focuses on monitoring the quantity and quality of rainwater in the sewage system at the wastewater treatment plant in Brno. These indicators have a direct impact on the safe operation of the sewerage system and wastewater treatment plants within the urban drainage. From this perspective, the work is focused on the evaluation of substance rainwater pollution discharged from busy traffic roads, both in the case of using of a single sewerage system for wastewater treatment and using a separate sewerage system that water to the recipient. To evaluate the function of the municipal sewerage system during extreme precipitation when the sewerage system is overloaded and wastewater overflows over the strain into the recipient. The contribution of the construction of one of the newly implemented retention basins was assessed. At the end of the sewerage system, ie.at the wastewater treatment plant, there were monitored changes in material composition, as well as the quantity and temperature of the influent wastewater during precipitation events, which affect the individual cleaning processes. In the conclusion, there is made an overall evaluation of the impact of precipitation water on drainage system of the city of Brno and its wastewater treatment plant. At the same time, there are evaluated newly designed concepts of drainage with respect to the already implemented measures for minimizing the impact of operational activities of sewerage system on the environment, especially the measures that aim to reduce the bag load of recipient.

Vyhodnocení účinnosti vybrané čistírny odpadních vod
Bedřichová, Klára
The diploma thesis deals with the evaluation of the efficiency of wastewater treatment at a selected wastewater treatment plant in Hodějice. It is used for the treatment of mostly sewage water from five municipalities. The aim was to obtain data on the water quality at the inflow and outflow from the WWTP based on its own monitoring, calculate the efficiency and to compare it with the data provided by the WWTP Hodějice in 2018. The relevant issue of pollution, wastewaters, their sewering and treatment is handled in literary review. The thesis also includes characteristics of the area of interest and selected wastewater treatment plant. The results were graphically processed and compared with the emission standards set out in government regulation no.401/2015 coll. and the water authority of Slavkov u Brna, listed in the Sewerage code of WWTP Hodějice. It was found that for the monitored indicators the efficiency of treatment is sufficient.

NK cells and KIR receptors: their importance in haematopoietic stem cell transplantations in leukemia
Ledvinková, Anna ; Vraná, Milena (advisor) ; Pačes, Jan (referee)
NK cells and KIR receptors: their importance in haematopoietic stem cell transplantations in leukemia Abstract This bachelor thesis discusses the importance of NK (natural-killer) cells in leukemias. It focuses on the structure and reactivity of NK cells, and especially on transmembrane KIR receptors (killer cell immunoglobulin-like receptors) of NK cells, that play an important role in the elimination of leukemic cells (graft-versus leukemia reaction, GvL) and thus in the overall prognosis of the disease. Activation and inhibitory receptors of KIR, by their cooperation, control the cytotoxic activity of NK cells. Thus, the typing of KIR receptor genes in hematopoietic stem cell donors can predict treatment success. KIR genes examination is mainly used in patients diagnosed with acute myeloid leukemia. Keywords: KIR receptor, NK cells, haematopoietic stem cell transplantation, HSCT, leukemia, donor, recipient
